I really like the way rigid rear projection screens looks. I want to recreate this in a diy application.

I have tried the following:
Sheet: you see too much sheet texture.
Shower curtain: hot spot/see curtain too much.
A number of frosted glass films: too transparent = hot spot. Too opaque = dim image. (There may be a sweet spot here but hard to tell with small inexpensive samples.)
Spray paint: not transparent.
Rolled latex Paint: way too much texture in paint.
Window tint: too transparent.
A number of tracing/vellum/drafting papers: (most promising of all materials)does not "pop" like the rear projection screen film sample I received from Solyx though. (which looks really good)
Frosted glass: can't find it with enough frost, too transparent.
The cheapest rear projection screen film I can find is $40 a foot x 60" plus I have to buy well over $100 worth of acrylic sheet.
Does anyone have screen shots of a diy rigid rear projection screen with details about it?
Does anyone have any suggestions as to how to accomplish this affordably?

The problem that you are facing is the 'rigid' part...

sliver/grey spandex is all I've found that's DIY and affordable.

This is mid afternoon with a floor to ceiling wall of glass washing the place with light.

What say you MM and PB?

Agreed.

You can stretch the Spandex across the back of Matte or "no glare" Acrylic to present a "TV look"

Everything else is more complicated...more expensive...or both.

BTW, JBJB.....that's pretty cool there.
How big is that?

is that a straight short throw? or are you bouncing the image off a mirror...

UST 80" no first surface mirror.
No hotspot, very even from corner to corner. The advantage of UST is that you are never in line to see the bulb.

apology for the out of focus crappy cell phone pic.

It was just some joann grey spandex. Considering the blinding amount of light from all the windows, I thought it turned out well.

PB/MM
Is there a silver/gray (rosebrand maybe) color that you think might work better for the OP? AKA, what's the best color of spandex to use for RP?
